The compound formed by P and Q
- i. follows the duet rule
- ii. forms covalent bonds
- iii. has a low melting point
Think it through first, then pick an option.
- a ii
- b i and ii
- c ii and iii
- d i, ii and iii
Answer and explanation
Correct answer: d i, ii and iii
P = H and Q = N: NH₃ follows the duet rule, is covalent and has a low melting point.
Why the other options are wrong
- a ii: i and iii are true too. The answer the book supports is i, ii and iii.
- b i and ii: iii is true too: a covalent compound has a low melting point.
- c ii and iii: i is true too: every atom holds electron pairs.
