The compounds 2-butanol and 2-butene both contain
(1) double bonds, only (3) carbon atoms
(2) single bonds, only (4) oxygen atoms



Answer :

The answer is (3) carbon atoms. For 2-butanol, it contains single bonds only and with C, O, H atoms. For 2-butene, it contains single bonds and double bonds both. And contains C, H atoms.

Answer:

(3) carbon atoms

Explanation:

2- butanol is a secondary alcohol containing C,H and O with a molecular formula: C4H10O and a structural formula: CH3CH2CH(OH)CH3

2- butene is an unsaturated hydrocarbon i.e. an alkene containing C and H only with a molecular formula: C4H8 and a structural formula:

CH3CH2CH=CH2

Based on the given options, the only common ground between 2-butanol and 2-butene is that both contain carbon atoms.
