Chemistry Question on Chemical bonding and molecular structure

The homologue of ethyne is

A

C2H2C_{2}H_{2}

B

C2H6C_{2}H_{6}

C

C3H8C_{3}H_{8}

D

C3H4C_{3}H_{4}

Answer

C3H4C_{3}H_{4}

Explanation

Solution

Ethyne is nothing but C2H2C _{2} H _{2} ie, acerylene which can be represented by general molecular formula CnH2n−2C _{n} H _{2 n-2}. Only C3H4C _{3} H _{4} tallies with the formula. Hence, C3H4C _{3} H _{4} is the homologue of C2H2C _{2} H _{2}
