Suggest reasonable explanations for each of the following observations:
The first-order rate constant for the solvolysis of (CH3)2CCHCH2Cl in ethanol is over 6000 times greater than that of allyl chloride (25°C).
After a solution of 3-buten-2-ol in aqueous sulfuric acid had been allowed to stand for 1 week, it was found to contain both 3-buten-2-ol and 2-buten-1-ol.
Treatment of CH3CHCHCH2OH with hydrogen bromide gave a mixture of 1-bromo-2-butene and 3-bromo-1-butene.
Treatment of 3-buten-2-ol with hydrogen bromide gave the same mixture of bromides as in part (c).
The major product in parts (c) and (d) was 1-bromo-2-butene.
