What is the name of this alkane? Two central carbons are bonded to C H 3 at each end, H below, and C H3 above the left carbon and H above the right carbon.

Answer:
the first alternative is the answer.
Explanation:
first u choose the longest chian. that is the horizontal chain. then u count the carbon number. then u see if there are alkyls the alkyl is methyl. and it is 1. so, you first write the alkyl number (1) then the alkyl name (methyl) then you write the alkane name (butane) because it consists 5 carbons. hope it helped.
The correct answer is 1-methyl butane.
Alkanes are a series of compounds that contain carbon and hydrogen atoms with single covalent bonds. These are known as saturated hydrocarbons. This group of compounds consists of carbon and hydrogen atoms with single covalent bonds.
While writing the IUPAC name the chain with the highest number of C atoms is considered to be the parent chain and since 1-methyl butane; methyl also forms the part of the chain so we shall use pentane (normal pentane and not 1-methyl butane) so literally, pentane and 1-methyl butane is the same molecule and not isomers.
