For example octane has eight carbon atoms and thus (2 x 8) +2 = 18 hydrogen atoms. We can thus recognise whether an ...

Aldehydes are usually more reactive than Ketones for two reasons: 1. steric and 2 electronic reasons Sterically, the presence of two bulky (large) groups in ketones will hinder the attack of nucleophile to carbonyl carbon in ketone. Aldehydes have only one bulky group around the carbonyl carbon and ...
