Question

Match column I with column II and pick the correct option from the codes given below:

Column I	Column II
p. Peroxy acetyl nitrate	1. Waste incineration
q. Polycyclic aromatic hydrocarbons	2. Global warming
r. Dioxins	3. Photochemical smog
s. Indigo	4. Carcinogens
t. IR active molecules	5. Vat dye

• A. p-3, q-4, r-1, s-5, t-2
• B. p-1, q-2, r-3, s-4, t-5
• C. p-3, q-5, r-1, s-2, t-4
• D. p-5, q-3, r-1, s-2, t-4

Answer 1

Answer: (A)

p-3, q-4, r-1, s-5, t-2

Solution:

p) Peroxy acetyl Nitrate: (3) It is a secondary pollutant present in photochemical smog

q) Polycyclic aromatic hydrocarbons: (4) Excessive exposure to polycyclic aromatic hydrocarbons (PAHs) often results in lung cancer

r) Dioxins: (1) When you incinerate waste, some dioxin formation is inevitable.

s) Indigo: (5) Vat dyes are a class of dyes that are classified as such because of the method by which they are applied. Vat dyeing is a process that refers to dyeing that takes place in a bucket or vat. The original vat dye is indigo.

t) IR active molecules: (2) Cause Global warming

Hence option A is correct
