Identify the addition reaction which is not undergone by the alkenes
Alkenes do not undergo mercuration, indeed they undergo oxymercuration , a process in which an alkene is converted into an alcohol.
Geometrical isomerism is a type of:
Geometric isomerism (also known as cis-trans isomerism 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.
Wide range of different hydrocarbons are separated into fractions
The hydrocarbons which condense over a temperature range (for example, between 50∘C and 100∘C), are called a fraction because they are parts of a whole. Each of the fractions has special uses.Separating the mixture of substances in crude oil into fractions by evaporation and condensation is fractional distillation.
Out of the following compounds , which will be have a zero dipole moment.
In case of trans-1,2-dichloroethylene
The net dipole moment is zero but in case of cis -1,2 -dicholorethylene.
There is some resultant dipole moment.
Due to presence of double bonds, alkenes are
Hydrocarbons are compounds made from carbon and hydrogen atoms joined by covalent bonds. Alkanes are saturated - they have only single bonds. Alkenes have a double bond - they are unsaturated. These polymer molecules are saturated.
