WebThe molar masses of CH 4, SiH 4, GeH 4, and SnH 4 are approximately 16 g/mol, 32 g/mol, 77 g/mol, and 123 g/mol, respectively. Therefore, CH 4 is expected to have the lowest boiling point and SnH 4 the highest boiling point. The ordering from lowest to highest boiling point is expected to be CH 4 < SiH 4 < GeH 4 < SnH 4.
WebNov 25, 2011 · Why is the boiling point of GeH4 higher than SiH4? Gernanium has an atomic number of 32 while silicon 14. This means GeH4 has more electrons than SiH4, therefore GeH4 has stronger Van der Waals ... Germane is the chemical compound with the formula GeH4, and the germanium analogue of methane.
