Alkynes are __________ in nature and first four members are __________

1.	Alkynes are __________ in nature and first four members are __________ gases.(a) polar, white(b) nonpolar, colourless(c) polar, colourless(d) nonpolar, whiteI had been asked this question in a national level competition.This intriguing question originated from Hydrocarbons topic in chapter Hydrocarbons of Chemistry – Class 11
Answer» Right option is (b) nonpolar, colourless The best I can explain: Alkanes being nonpolar in nature, soluble in nonpolar solvents but insoluble and polar solvent such as WATER. The first four members of alkanes are colourless gases, the NEXT 13 members are colourless liquids and next HIGHER members are colourless solids, this can be explained on the basis of the MAGNITUDE of attraction forces.
