Question

Which of the following pairs are correct?

• A. Saturated Compounds - Yellow Flame, Unsaturated Compounds – Clean or blue Flame
• B. Saturated Compounds- Clean or blue Flame, Unsaturated Compounds – Yellow Flame
• C. Saturated Compounds and Unsaturated Compounds both give yellow flame
• D. Saturated Compounds and Unsaturated Compounds both give Clean or Blue flame

Answer 1

The correct option is B

Saturated Compounds- Clean or blue Flame, Unsaturated Compounds – Yellow Flame

The unsaturated compounds contains double and triple bonds which are not easy to break. Therefore, these compounds give yellow flame due to their incomplete combustion.

The saturated compounds are composed entirely of single bonds which are easy to break. Therefore, these compounds give blue flame due to complete combustion.

Hence, the correct pair is:
Saturated Compounds- Clean or blue Flame,
Unsaturated Compounds- Yellow Flame.
