Hi, thank you for the suggested answer,
May I know why is qn 1 b not c?
Qn 4, why cannot d? Metallic bonding depends on both delcalised
electrons and charge.
39, if alkaline kmno4, wouldn't it not oxidise?
Q1. C is wrong because you need to fill the 2s orbital before you
fill the 2p orbital.
Q4. Magnitude of cationic charge is the most important factor. Even
considering no. of delocalized electrons, Ca2+ still as more
delocalized electrons available for metallic bonding than Na+
(inner shell electrons are irrelevant).
Q39. It's not about oxidation (since heating under reflux wasn't
specified), it's about alkaline solution deprotonates phenol.
