The question is : Some simple organic compounds are shown. some structures are correct, but some have the wrong number bonds. Classify the compounds based on whether they show correct bonding or incorrect bonding. Please help, ASAP

1- Correct bonding

2- Incorrect bonding

3- Correct bonding

4- Incorrect bonding

Explanation:

1. Structure 1 is called formaldehyde or methanal as it shows the alkanal functional group (-CHO). The structure has a trigonal shape with one central carbon single bonded to two hydrogen atoms and double-bonded (=) to an oxygen atom. Hence, it shows correct bonding.

2. Structure 2 depicts a member of carboxylic group with a carboxylic acid functional group (-COOH). The carboxyl group has a carbon atom double-bonded to an oxygen atom (C=O) and single bonded to an hydroxyl group (OH). However, the structure is trying to depict ACETIC ACID, which has a methyl group (CH3) attached to its carboxyl group (COOH). One hydrogen is missing from the bonding, hence, it shows incorrect bonding.

3. Structure 3 is ETHANOL with an hydroxyll group. It is the second member of the alcohol group with an ethyl group (C2H5) attached to its alcohol functional group (-OH). Hence, it has chemical formula C2H5OH. The structure in the question shows correct bonding.

4. Structure 4 shows incorrect bonding because a carbon atom can only form FOUR covalent bonds with atoms of other elements (it has only four valence electrons). In this structure, five hydrogen atoms are attached to one carbon atom, which is chemically impossible.
