NEET2006ChemistryAlcohols Phenols and EthersActual
The major organic product in the reaction, CH ₃- O - CH ( CH ₃ )₂+ HI products is:
Options
- ACH ₃ I + ( CH ₃ )₂ CHOH
- BCH ₃ OH + ( CH ₃ )₂ CHI
- CICH ₂ OCH ( CH ₃ )₂
- D( array c CH ₃ OC ( CH ₃ )₂ | I array )
Correct answer
A. CH ₃ I + ( CH ₃ )₂ CHOH
Step-by-step solution
In the case of an unsymmetrical ether, the alkyl halide is always formed from the smaller alkyl group. This happens because the I ⁻ ion being larger in sizc approaches the smaller alkyl group to avoid steric hindrance. Caution H I is an acid and when it is hot and concentrated it means we are having an excess of HI . Iodide ion produced from HI in this reaction will act as a nucleophile.
