Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If an alkane has 10 carbon atoms, how many hydrogen atoms will it have?
A
20
B
22
C
40
D
42
Explanation: 

Detailed explanation-1: -Hence, for an alkane having ten carbon atoms, there are (2×10)+2=22 hydrogen atoms.

Detailed explanation-2: -AI Recommended Answer: There are 18 carbon atoms in the unbranched alkane with 22 carbon atoms.

Detailed explanation-3: -Decane is a hydrocarbon that has 10 carbon and 22 hydrogen atoms covalently bonded to one another. With a molecular formula of C10H22 C 10 H 22, decane represents a type of alkane. Alkanes are hydrocarbons in which only single bonds are present between the carbon and hydrogen atoms.

Detailed explanation-4: -Cyclodecane is a ring of ten carbon atoms.

Detailed explanation-5: -There are 12 ends or bends, so this molecule has 12 C atoms. Alkanes have a general formula of CnH2n+2, meaning there are 2(12) + 2 = 26 H atoms.
