Give the structure corresponding to the iupac name 2−sec−butyl−4,4−diethylnonanoic acid

The structure of 2-Sec-butyl-4,4-diethylnonanoic acid is attached below,

The structure was drawn using following information.

1) First, the parent chain was identified, as the parent name is specified at the end of the name, so it was found to be nonanoic acid. The nonane specifies the number of nine carbon atoms and -ic acid specifies that the parent compound is carboxylic acid with nine carbons.

2) Secondly, the substituents were added as follow,

                       a) At alpha position (2nd carbon next to carbonyl carbon) a sec-butyl group was added.

                       b) At carbon 4, two ethyl groups were added, as the number 4,4 shows double substitution of same substituent.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
