Answer:

Plucking occurs when rocks and stones become frozen to the base or sides of the glacier and are plucked from the ground or rock face as the glacier moves. HOPE THIS HELPS!~

Answer:

Abrasion occurs when the ice sheet scours and wears away at the underlying rock, gradually wearing it down over time. Plucking occurs when the chunks of rock become bonded to the ice sheet, so that when the ice sheet moves it carries the chunks of rock with it. Both of these processes wear away a rock body until a distinct formation develops. In this case, a glacier horn may develop.

Which 2 resonance forms destablize the carbocation intermediate if bezonitrile undergoes chlronation at the ortho or para positi

Anna11 [10]

The question is incomplete, the complete question is shown in the image attached

Answer:

A and B

Explanation:

The electrophilic substitution of arenes yields a cation intermediate. The positive charge of the cation is delocalized over the entire ring.

The -CN group directs incoming electrophiles to the ortho/para position. The resonance structures for the chlorination of benzonitrile are shown in the question.

Recall that -CN is an electron withdrawing group. The resonance forms that destablize the carbocation intermediate are those in which the -CN group is directly attached to the carbon atom bearing the positive charge as in structures A and B.
