Answer 1

1) ) CBr₄ has a higher boiling point than CCl₄: True

2 CBr₄ has weaker intermolecular forces than CCl₄: False

3) CBr₄ has a higher vapor pressure at the same temperature than CCl₄: False

4) CBr₄ is more volatile than CCl₄: False

Step-by-step explanation:

1) ) CBr₄ has a higher boiling point than CCl₄: True :

Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger and thus it need more temperature to boil it off.

2 CBr₄ has weaker intermolecular forces than CCl₄: False

Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger.

3) CBr₄ has a higher vapor pressure at the same temperature than CCl₄: False

Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger. Thus the vapor pressure of it will be less than CCl₄ at the same temperature.

4) CBr₄ is more volatile than CCl₄: False

Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger. Thus CCl₄ is more volatile.
