Question 17

What are cycloalkanes normally used for

Answer 17

fuels

Question 18

Explain why melting and boiling points increase as molecular size increases

Answer 18

As molecular size increases stronger forces of attraction form between the molecules so more energy is needed to seperate them

explain why acids are soluble in water

Answer 19

It can form intermolecular attractions with water molecules
