Final answer:

This question asks to draw the Lewis structures and describe the molecular geometry of three organic compounds.

Step-by-step explanation:

For each of the given compounds:

a) ch3coch2chchcooh

- The Lewis structure of the compound is as follows:

H3C - C(=O) - CH2 - C(CH3) - CH2 - COOH

- The bond angles around each carbon atom are approximately 109.5 degrees, indicating a tetrahedral geometry.

- Each carbon atom in the compound exhibits sp3 hybridization.

b) ch3ch2c(ch3 )2ch2cooch3

- The Lewis structure of the compound is as follows:

H3C - CH2 - C(CH3)2 - CH2 - COOCH3

- The bond angles around each carbon atom are approximately 109.5 degrees, indicating a tetrahedral geometry.

- Each carbon atom in the compound exhibits sp3 hybridization.

c) ncch2coch2cho

- The Lewis structure of the compound is as follows:

N≡C - CH2 - C(=O) - CHO

- The bond angles around the carbon atoms vary depending on the number and type of atoms bonded to them.

- The carbon atom bonded to the nitrogen atom exhibits sp hybridization, while the other carbon atom exhibits sp2 hybridization.
