Explanation:
Answer:
Aluminum (Al)
Explanation:
1. You wrap a sandwich in aluminum foil
2. Aluminum is on the periodic table.
The bigger molecule has more interactions and hence the higher b.p. CH3CH2OCH2CH3 is a bigger molecule than CH4 and CH3CH3, so has more dispersion forces. It also has dipole-dipole forces due to the polarised C-O bonds. CH3OH and CH3CH2OH have hydrogen bonds due to the very electronegative O atom bonded to the H atom
