Question 6

WHAT IS TAMOXIFEN ?

Answer 6

A common drug used to treat breast cancer - is a hormone receptor-positive (hormone positive)

Question 7

What are the 4 steps to systemic naming of organic compounds ?

Answer 7

1) PREFIX = number of substituents, functional groups etc.
2) PARENT = length, longest continuous carbon chain.
3) INFIX = unsaturation of main chain e.g. single, double, triple C-C bond.
4) SUFFIX = dominant functional group and where it is positioned

Question 8

What is a primary alcohol ?

Answer 8

When the carbon is attached to the OH group and has one other carbon attached to it e.g. H3C—OH

Question 9

What is a secondary alcohol ?

Answer 9

When the carbon attached to the OH has two other carbons attached to it e.g. C—CH2—OH

Question 10

What is a tertiary alcohol ?

Answer 10

When the carbon attached to the OH has three other carbons attached to it.
