Answer 3

A compound in which there is at least one double and/or triple bond between carbon atoms

Question 4

Functional group

Answer 4

An atom or a group of atoms that form the centre of chemical activity in the molecule

Question 5

Homologous series

Answer 5

A series of similar compounds which have the same functional group and have the same general formula, in which each member differs from the previous one by a single CH2 unit

Question 6

Structural isomers

Answer 6

Compounds having the same molecular formula but different structural formulae

Question 7

Uniqueness of carbon

Answer 7

1) carbon has the ability to form very long carbon-carbon chains, which are stable

2) carbon forms multiple bonds which are strong
