Question

which of the following alkane is liquid at room temperature?
1 C4H10
2 C10H22
3 C22H46
4 C45H94​

Answer 1

Answer:

c10h22 is liquid....

Explanation:

that's because carbon content is more.if it is less then in gas phase and if more then solid state.

Answer 2

Answer:

An important class of binary compounds are the hydrocarbons. As the name implies hydrocarbons consist of only hydrogen and carbon atoms. There are thousands of possible hydrocarbon molecules. However, the simplest type are called "alkanes". Alkanes have the formula CnH2n+2, where n = 1,2,3 etc.. For example for n=1 we have CH4, for n=2 we have C2H6 etc.. Naming these hydrocarbons is simple:

For n=1-4 the names have historical importance and must therefore be memorized.

For n > 4 the first part of the name gives the number of carbon atoms (e.g., n=5 is pent-, n=6 is hex- etc.)

the lastpart of the name ends with "- ane"
