NEETChemistryHydrocarbons
Why are the first four members of alkanes (C1 to C4) in the gaseous state at 298 K?
Options
- AHigh electronegativity of carbon atoms
- BLow molecular mass
- CPresence of hydrogen bonding
- DStrong van der Waals forces
Correct answer
B. Low molecular mass
Step-by-step solution
The first four members of alkanes (C1 to C4) are in the gaseous state at 298 K because of their low molecular mass and weak intermolecular forces.
