How can Nylon burn with the smell of burning hair??

Ans 2:

Class : Class 8
Correct answer is A

Ans 3:

Class : Class 8
Nylon does not have the smell of burning hair. So the answer should be d.

Ans 4:

Class : Class 9
Supposed to be D

Ans 5:

Class : Class 9
yes the answer is D. nylon burns with a smell of celery because its a synthetic fibre.

Ans 6:

Class : Class 8
How is this possible Nylon burns with smell of hair???

Ans 7:

Class : Class 8
Nylon should neither have a smell of burning hair nor the smell of burning paper. Nylon has a celery or plastic-like cell. Hence the correct answer is D. But on the other hand when acrylic burns, it shrinks and converts into black beads. On this contrast, the correct answer will be B with respect to acrylic and D with respect to Nylon. There is definitely an error in the options of the answers!

Ans 8:

Class : Class 9
wrong answerthe answer should be B

Ans 9:

Class : Class 9
IT must be D! Nylon does not burn with the smell of burning hair as it is purely synthetic and has no relation to the protein based hair.
