Classify the carbohydrate tagatose by both the carbonyl group and the number of carbon atoms. D-tagatose is sugar with six carbon atoms. The Fischer projection shows C1 is achiral with one OH group, C2 is the location of the carbonyl, C3 and C4 have OH groups on the left, C5 has an OH groups on the right, and C6 is achiral. Enter the classification (e. g., aldotriose).

Hexose category and ketohexose category

Explanation:

The classification of the Carbohydrate tagatose by carbonyl group is that it is a monosaccharide and has a hexose structure hence it belongs to the Hexose category

Based on the number of carbon atoms the structure has a ketofunctionality hence it is classified under the ketohexose category

Attached below is the remaining part of the solution

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
