The amide ion NH2- is a base which can only be used in which one of the solvents shown below: A) Ch3OH B) CH3CH2OH C) H2O D) D2O E) Liquid NH3
Solutions
Expert Solution
answer : E ) NH3
explanation:
here we know that NH2- is strong base . if we want to use solvent for this nucleophile we should select which is having same ion compound. here NH3 is base and it is having NH2- also . so it is better solvent .
if we use any other mentioned above. those can act as acids and NH2- base. so NH2- nature will lost by acid base reaction .
CH3OH + NH2- ------------> CH3O- + NH3
CH3CH2OH + NH2- ------------> CH3CH2O- + NH3
H2O + NH2- -------------------> NH3 + OH-
D2O + NH2- ------------------> NH2D + OD-
another example :
for CH3CH2O - the solvent we need to use CH3CH2OH

Polystyrene has been shown to be soluble in certain terpinene
solvents. From the evidence below, determine the enthaply of
vaporization of the terpinene. (a) Dissolving 2.86 mL of benzene in
50.0 g of the terpinene raises the boiling point from 174.8◦C to
177.53◦C. (b) Dissolving 2.14 g of the terpinene in 30 mL of
benzene increases the boiling point of benzene to 355.8K. (c)
