1.	The correct order of boiling point for primary (1^(@)), secondary (2^(@)) and tertiary (3^(@)) alcohols is
Answer» `1^(@) gt 2^(@) gt 3^(@)` `3^(@) gt 2^(@) gt 1^(@)` `2^(@) gt 1^(@) gt 3^(@)` `2^(@) gt 3^(@) gt 1^(@)` Solution :Alcohols with same mol. Wt are EXPECTED to have almost same b.p., HOWEVER, TWO more FACTORS other than mol. wt. are important, they are namely H-bonding and surface area of molecule. Both these factors are least in `3^(@)` alchols and maximum in `1^(@)` alcohols. Hence `3^(@)` alcohols have least b.p. while `1^(@)` alcoholshave maximum b.p.
