Detailed explanation-1: -Carbohydrates are made of Nitrogen, Carbon and Hydrogen. Ans-False. Explanation-Carbohydrates are made of Oxygen, Carbon and Hydrogen.
Detailed explanation-2: -Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements.
Detailed explanation-3: -This view represents these molecules simply as “hydrated” carbon atom chains in which water molecules attach to each carbon atom, leading to the term “carbohydrates.” Although all carbohydrates contain carbon, hydrogen, and oxygen, there are some that also contain nitrogen, phosphorus, and/or sulfur.
Detailed explanation-4: -All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates. Glucose, for instance, is a single-unit carb with six carbon atoms, 12 hydrogen atoms and six oxygen atoms.
Detailed explanation-5: -Carbohydrates are polar molecules that are composed of carbon, hydrogen, and oxygen and carbohydrates have polar hydroxyl functional groups in the molecule.
