Choose the substance with the highest vapor pressure at a given temperature:a. SiS2b. RbClc. CH3SCH3d. BF3e. SbH3

Respuesta :

Answer:

correct option is d. BF3

Explanation:

BF3 have lower molecular weight than the SiS2 and CH3SCH3  

but it has a more attractive force

and here dispersion forces is the weakest in BF3  

but CH3SCH3 have dipole forces

In Bf3 have only vanderwaal force and it holds the molecule together in liquid but it not have hydrogen bonding  

and at 0°C  substance is in gas no liquid and no vapour  

so here correct option is d. BF3
