The reaction in an experiment is the Wittig synthesis of 1,4-Diphenyl-1,3-Butadiene, and one of the questions is:
In the reaction for this experiment, carbon is nucleophilic. Why is carbon not ordinarily nucleophilic?
What allows the carbon to remain in solution long enough to react in the way described by the Wittig reaction?

Explanation:

Due to the presence of phenyl groups and diene, the aromaticity prevails and the nucleophilic carbon becomes part of aromaticity which increases the stability of entire compound. Therefore, the nucleophic carbon is considered

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
