Why pyrrole synthesis is unimportant

A. Introduction

pyrrole may be prepared in the laboratory of by the classic method of heating the ammonium salt of mucic acid with I substituted pyrrole such as I - phenylpyrrol can be conveniently obtained by heating mucic acid with the appropriate Amine

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
