Question

C3H8 belongs to the homologous series of

(a ) Alkynes
(b ) Alkenes
(c ) Alkanes
(d ) Cycloalkanes​

Answer 1

The correct answer is:

(C) Alkanes.

C3H8 represents propane, which is a member of the homologous series of alkanes. Alkanes are hydrocarbons with single covalent bonds between carbon atoms and have the general formula CnH2n+2, where "n" represents the number of carbon atoms in the molecule. Propane has three carbon atoms, so its molecular formula is C3H8.

Answer 2

• (c ) Alkanes

Step-by-step explanation:

The reason is that alkanes are saturated hydrocarbons composed of single covalent bonds between carbon atoms. C3H8 specifically represents propane, which has three carbon atoms and eight hydrogen atoms, and all the carbon-carbon bonds in propane are single bonds, making it an alkane. Alkenes contain at least one carbon-carbon double bond, alkynes contain at least one carbon-carbon triple bond, and cycloalkanes are cyclic alkanes. However, since C3H8 has only single bonds, it falls into the category of alkanes.
