Assertion: Replacement fo -Cl group by -OH in chlorobenzene is easier if nitro group is present in the ring.
Reason: Nitro group leads to strengthening of the C-Cl bond in chlorobenzene.

A

`NO_(2)` dontes `e^(-)` at meta position

B

`NO_(2)` withdraws `e^(-)` from ortho/para positions

C

`NO_(2)` make ring electron rich at ortho & para

D

`NO_(2)` withdraws `e^(-)` from meta position

Presence of a nitro group in a benzene ring

Name the functional group present in C_2H_5Cl .

Assertion: It is difficult to replace chlorine by -OH in chlorobenzene in comparison to that in chloroethane Reason: Chlorine-carbon (C-Cl) bond in chlorobenzene has a partial double bond character due to resonance.

Assertion (A) Nitration of chlorobenzene leads to the formation of m-nitrochlorobenzene. Reason (R) -NO_(2) group is a m-directing group.

Assertion The d_(C-O) in bridging carbonyl geroup is longer than that of terminal carbonyl group Reason With increase in extent of synergic bonding the C-O bond length increases .

Assertion: cis-form of alkene is found to be more polar than the trans-form. Reason: Since the groups are in opposite directions in the trans-form, the dipole moments of bonds cancel each other making trans-form almost non-polar.

Assertion (A) Presence of a nitro group at ortho or para position increases the reactivity of haloarenas towards nucleophilic substitution. Reason (R ) Nitro group, being an electron withdrawing group decreases the electron density over the benzene ring.

Assertion: The second substituent may enter the mono-substituted benzene ring at either ortho, para or at meta position. Reason: The position of the incoming group is determined by the natrue fo the group present in monosubstituted benzene ring.
