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 correct Pair:
Saturated Compounds- Clean or blue Flame,
Unsaturated Compounds – Yellow Flame.

This change in colour of flame happens due to the incomplete combustion of unsaturated compounds. The saturated compounds are composed entirely of single bonds saturated with hydrogen.
