Q. Consider the following pairs:
| Chemical |
Common Use |
| Phenol |
Explosives |
| Toluene |
Antiseptic (carbolic acid) |
| Naphthalene |
Mothballs |
How many of the above pairs are correctly matched?
Answer:
Only One Pair
Notes: Phenol is used as an antiseptic (carbolic acid), not for explosives. Toluene is used in explosives (TNT), not as an antiseptic. Naphthalene is used in mothballs, which is correct. Therefore, only one pair is correctly matched.
