Answer:
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
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.
