Answer 1

(1)

Explanation:

Acetylene burns with a sooty flame because it has a high proportion of carbon and undergoes incomplete combustion. Therefore, the Assertion (A) is true.

Acetylene has a greater carbon content compared with saturated hydrocarbons of similar size. Therefore, the Reason (R) is also true.

Hence, both A and R are true and R is the correct explanation of A.
