When numbering a carbon chain, how should you number it to ensure substituents have the smallest possible numbers?

• From bottom to top

• From left to right or right to left, depending on substituent positions

• From top to bottom

• From right to left

In the context of naming alkanes, what does the term 'parent chain' refer to?

• The chain with the most substituents

• The chain with the most hydrogen atoms

• The chain with the highest molecular weight

What is the correct way to indicate the position of a substituent in a molecule's name?

• By writing the substituent's name followed by the position number

• By writing the position number followed by a dash and the substituent's name

• By using a suffix

• By using a prefix

What prefix is used when there are two identical substituents on a molecule?

• Tetra
