Each molecule of compound Q has three double bonds. $\text{CH}_2{=}\text{CH}{-}\text{CH}_2{-}\text{C}(=\text{O}){-}\text{CH}_2{-}\text{C}(=\text{O}){-}\text{OH}$ Using hot, concentrated acidified $\text{KMnO}_4$, which bond, X or Y, is broken, and how many lone pairs of electrons are there in one molecule of Q?
- ABond ruptured: X; number of lone pairs: 5
- BBond ruptured: X; number of lone pairs: 6
- CBond ruptured: Y; number of lone pairs: 5
- DBond ruptured: Y; number of lone pairs: 6
