Question

Define the definition of the following with examples. 1.) Conformations 2.) Geometric isomers or Cis trans isomers 3.) Dipole moment

Answer 1

2 ) Geometric isomerism (also known as cis-transisomerism or E-Z isomerism) is a form of stereoisomerism. This page explains what stereoisomers are and how you recognise the possibility of geometric isomers in a molecule.
1) Conformation generally means structural arrangement and may refer to: Conformational isomerism, a form of stereoisomerism in chemistry. Carbohydrate conformation. Cyclohexane conformation. Protein conformation.
3)  When atoms in a molecule share electrons unequally, they create what is called a dipole moment.
