Which of the following reagents convert(s) benzoyl chloride to phenyl propyl ketone?

a. ch3ch2ch2mgbr
b. ch3ch2ch2li
c. (ch3ch2ch2)2culi
d. both a and b
e. both a and c

c. (CH3CH2CH2)2CuLi

Explanation:

(CH3CH2CH2)2CuLi

This reagent is called Lithium di(n propyl)cuprate used to covert benzoyl chloride to phenyl propyl ketone. this reagent is called Gilman Reagent and The reaction occur with nucleophilic substitution of an alkyl group for the leaving group (chloride), forming one new carbon-carbon bond.

Hence the correct answer is C that is   c. (CH3CH2CH2)2CuLi

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

the answer for sodium is 0.186

the answer for rubidium is 0.251
