Organic Chemistry

Question 1

What is a functional group

Answer 1

This is a group of bonded atoms that gives an organic compound is characteristic chemical properties.

Question 2

Why are organic compounds classified on the basis of functional group

Answer 2

for easy identification, for the study of the characteristic properties of the members of a particular group

Question 3

Define homologous series

Answer 3

There are a series of organic compounds with similar structural features but differ from adjacent members by a methelene unit

Question 4

State two characteristics of a homologous series

Answer 4

They can be represented by a general molecular formula, all members have similar chemical properties, the differ from each neighboring member by 14 a.m.u, all members show a gradual change in physical properties, best of the group have same functional group

Question 5

What is a hydrocarbon

Answer 5

This is a compound containing hydrogen and carbon only

Question 6

Define isomerism

Answer 6

This is the occurrence of two or more compounds with the same molecular formula my different molecular structures or structural formula

Question 7

Define isomers

Answer 7

This is compound to the same molecular formula but different structural formula

Question 8

What is an aliphatic compound

Answer 8

Organic compounds with carbon atoms arranged in open chains or straight chain cyclic.

Question 9

Define aromatic compounds

Answer 9

they are organic compounds containing benzene rings

Question 10

State two properties of Carbon that is responsible for its ability to form mini compounds

Answer 10

It’s ability to catenate, to form isomers, it has four electrons in its valence shell and are available to form bonds, it can combine with so many other elements, it can form single double and triple carbon carbon bonds

Question 11

What hybridization do carbon atoms in alkanes undergo

Answer 11

SP3 hybridization
