The type of isomerism exhibited by cis and trans isomers is?
positional
geometrical
functional
optical
Correct answer is B
- Cis–trans isomerism, also known as geometric isomerism or configurational isomerism arises when atoms or groups are arranged differently in space due to restricted rotation of a bond or bonds in a molecule.
The following molecules have double covalent bonds between two atoms except?
oxygen
carbon (IV)oxide
ethene
water
Correct answer is D
In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
