The answer is “has a double C-C bond” i just took the test and got it right
The hydrocarbon has a double C-C bond. Explanation: Degree of unsaturation is a calculation that allows to know the number of rings and π-bonds. For a hydrocarbon of formula CₓHₙ, the degree of unsaturation is: For C₆H₁₂: = 1. As the hydrocarbon is a straight-chain hydrocarbon, there are not rings, thus, degree of unsaturation is due 1 π-bond, that means that hydrocarbon has a double C-C bond. I hope it helps!

2. Alkenes are also hydrocarbons. But they have at least one double bond. The general formula for the alkenes is CnH2n. Since, it has double bond, alkenes are unsaturated hydrocarbons. The hybridization of C which has double bond is sp². Due to the unsaturation it is a reactive hydrocarbon but less stable than alkanes. Hence, the false statement is “They are more stable than alkanes.” 3. Butene would have 4 carbon atoms and a double bond.
Butene is an alkene. Since the general formula of alkene is CnH2n, formula for
the butene is C4H4 because n = 4. It is an unsaturated hydrocarbon due to the
presence of the double bond. The double bond is made from one σ bond and one π bond. 4. Alkenes generally undergo addition reactions. Alkenes are unsaturated hydrocarbons which have double bonds. The hybridization of the carbon atom which has the double bond is sp². Hence, that double bond has one σ bond and one π bond. In addition reactions, the π bond breaks down and another atom is connected to the carbon atom by forming a σ bond. By undergoing addition reaction, the hybridization of c atom which has double bond changes from sp² to sp³. 5. If the carbon atom of hydrocarbon is bonded to less than 4 other atoms, the hydrocarbon is considered unsaturated. Maximum number of bonds that a carbon atom can form is 4. Those bonds can be formed by forming single bonds with four another atoms of by forming one double bond and two single bond with three atoms or by forming one single bond and one triple bond with to another atoms. The single bonds are saturated and double bonds and triple bonds are considered as unsaturated. 6. Unsaturated hydrocarbons have double bond and triple bonds as their functional groups but
saturated hydrocarbons have only single bonds. Due to the unsaturation, they will
react readily with other elements and compounds. Although the hydrocarbons are unsaturated, they also have
isomers. But the stability of the unsaturated hydrocarbons is less than saturated
ones. 7. Alkenes have the general formula as CnH2n. Hence C5H10 is an alkene which has 5 carbon atoms. Since, it is an alkene, that hydrocarbon has a double C-C bond. Since it is an unsaturated one, it is highly reactive than alkanes and unstable. It is less inert than alkanes. 8. The general formula of alkenes is CnH2n. Alkanes have the general formula as CnH2n+2 and for the alkynes, it is CnH2n-2. The general formula of alkenes and alkynes are given when there is only one double bond or triple bond. Due to the presence of double bonds and triple bonds, alkenes and alkynes are less stable and unsaturated. 9. Benzene is a cyclic closed ring and aromatic alkene. The general formula is CnH2n. Benzene has three double bonds. Hence, three C-C have double bonds which share 2 pairs of electrons. Since, those C-C bonds are double bonds, they have π bonds. The all of C atoms in benzene are sp² hybridized. Hence, all C atoms are actually identical. 10. 1. H-C≡C-H is a alkyne which has two carbon atoms. Hence, the name of this is ethyne. 2. Benzene is a cyclic compound which has both saturated and unsaturated characteristics. 3. The general formula of the alkenes is CnH2n. 4. addition is the typical reaction type for the unsaturated hydrocarbons. 5. The general formula of the alkynes is CnH2n-2. 6. series name of hydrocarbons with triple bond is alkyne. 7. The general formula of the alkenes is CnH2n+2.
b Explanation: got it right on edge 20202,hope this helps! (: (: (: (:
It is a complex, folded chain that helps regulate cell processes”. The monomers of a protein are amino acids. Many amino acids form a long linear chain to become peptides which is the primary structure of a protein molecule. Explanation:
2 nd statement is a better one… Explanation: We know most of the biologically active protein are folded in nature, and their native 3D structure is so much crucial in their various functions. Also, proteins regulate various cellular activities.
The second option is the best answer. Proteins are complex polymers of amino acids. They are folded into 3 dimensional structures . This folding defines not only the size and shape of the protein, but also its function. The folding of a protein allows for interactions between amino acids that may be distant from each other in the primary sequence of the protein. In enzymes, some of these amino acids form a site in the structure that catalyzes the enzymatic reaction. This site is called the active site.
Explanation: 1) Pentyne is an unsaturated hydrocarbon with formula . It is an alkyne molecule with single triple bond present in it. Correct statements are: Contains 5 carbonsHas a triple bond
Is an alkyne 2) Alkenes are unsaturated hydrocarbons with double bonds. They are unsaturated.They are reactive.
They have double bonds. 3) Butene is an unsaturated hydrocarbon with 4 carbon atoms and double bonds. 4)Alkene undergo addition reaction easily. 5)If the carbon atom of hydrocarbon is bonded to less than 4 other atoms, the hydrocarbon is considered unsaturated. 6)The correct statements are: They have double and triple bonds.
They will react readily with other elements and compounds. 7)The general formula of : Alkane = Alkene = Alkyne = The is an alkene with double C-C bond. 8) The general formula of alkene is given by: 9) Benzene is an aromatic cyclic compound with six membered carbon ring with alternative double bonds. Due to conjugation of double bond all the C-C bonds are identical. All C-C bonds share 2 pairs of electrons.All of the C-C bonds are actually identical.The structure of the molecule is closed like a ring structure.
has two double C-C bonds Explanation: A saturated compound is a compound having the full complement of hydrogen atoms for every carbon atom while an unsaturated compound does not contain the full complement of hydrogen atoms for every atom of carbon. If we look at C3H4, the only possible structure of the compound is H2C=C=CH2. We can see from this arrangement that the compound contains a cumulative double bond. This is the specific structure that fits into one of the descriptions in the options, the compound contains two double bonds.
