Question

The homologue of ethyne is: (A)  C2H2  (B)  C2H6  (C)  C3H8  (D)  C3H4

Tardigrade Admin · Accepted Answer

Ethyne is nothing but textC text2 textH text2 i.e., acetylene Which can be represented by general molecular formula textC textn textH text2n-2. Only textC text3 textH text4 tallies with the formula. Hence, textC text3 textH text4 is the homologue of textC2 textH2.

Q. The homologue of ethyne is:

$C_{2} H_{2}$

$C_{2} H_{6}$

$C_{3} H_{8}$

$C_{3} H_{4}$

Ethyne is nothing but $C_{2} H_{2}$ i.e., acetylene Which can be represented by general molecular formula $C_{n} H_{2n - 2.}$ Only $C_{3} H_{4}$ tallies with the formula. Hence, $C_{3} H_{4}$ is the homologue of $C_{2} H_{2} .$

Q. The homologue of ethyne is:

C2​H2​

C2​H6​

C3​H8​

C3​H4​

Ethyne is nothing but C2​H2​ i.e., acetylene Which can be represented by general molecular formula Cn​H2n−2.​ Only C3​H4​ tallies with the formula. Hence, C3​H4​ is the homologue of C2​H2​.

$C_{2} H_{2}$

$C_{2} H_{6}$

$C_{3} H_{8}$

$C_{3} H_{4}$

Ethyne is nothing but $C_{2} H_{2}$ i.e., acetylene Which can be represented by general molecular formula $C_{n} H_{2n - 2.}$ Only $C_{3} H_{4}$ tallies with the formula. Hence, $C_{3} H_{4}$ is the homologue of $C_{2} H_{2} .$
