Question

Order of +m effect Mesomeric effect

Answer 1

$\huge{\sf{\underline{AnswEr:-}}}$

The mesomeric effect as a result of p-orbital overlap has absolutely no effect on this inductive effect, as the inductive effect has purely to do with the electronegativity of the atoms and their topology in the molecule.

Answer 2

Answer:

Explanation:

order of +m effect is same as order of +i effect

if you want compare the +m effect compare +i effect it will be same

but before comparing the compounds +m effect check the compounds to the system should have lone pair or negative charge on it

after compare the compounds

for example

c6h5nh2 and c6h5nh3

in above second does not have lone pair so 1>2 order of +m effect

if both have lone pairs

c6h5nh2 and c6h5ch2

in above compare +i effect for +m effect

so compare +i effect order in nh2 and ch2

as it is +i effect the central atom should be electronegative

so nh2>ch2 and +m effect order is c6h5nh2>c6h5ch2
