1) In a 1-butanol molecule, what part of the molecule is described as hydrophobic? 2) Arrange the following alcohols in order of increasing boiling point 3) Provide the major organic product of the following reaction Na 4) Provide the major organic product of the reaction below or CH,CHCH.MBr (2 eq 2 H,O 5) Provide the major organic product of the following reaction. OH 1. TsCL. pyridine 2. NaBr 6) Provide the major organic product of the reaction shown. NaCrO HSO, 7) How many peaks appear in the proton spin decoupled 13 CNMR spectrum of the compound below? A) 1 B) 2 C)3 D) 4 E) 5

Explanation / Answer

Ans 1 :

As we know that the hydrophobicity of the alcohol increases as its size increases with the addition of carbon atoms, indicating that the alkyl groups are highly hydrophobic in nature. These groups are highly water hating/repelling , hence are called as hydrophobic.

The compound 1-butanol is CH3CH2CH2CH2OH , so here the hydrophobic part is butyl group , i.e. CH3CH2CH2CH2-
