Which of the following sugars is a product of the condensation of monosaccharides?
galactose
maltose
glucose
fructose
Correct answer is B
Maltose is produced by the enzymatic hydrolysis of starch (a homopolysaccharide) catalyzed by the enzyme amylase.
The by-product of fermentation of sugar is
carbon(IV) oxide.
ethanoic acid.
propanol
propan-1, 2, 3- triol.
Correct answer is A
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products
The IUPAC nomenclature of the structure is?
3-chloro-3-methylbutane
2,2,-dichloro-3-methylbutane
3-methylchlorobutane
2-chloro-2-methylbutane
Correct answer is D
Straight-chain hydrocarbon molecules that contain only singly-bonded carbons are called alkanes.
When naming these molecules, the final syllable in their name is "ane."
- Find and name the longest continuous carbon chain.
- Identify and name groups attached to this chain.
- Number the chain consecutively, starting at the end nearest a substituent group.
- Designate the location of each substituent group by an appropriate number and name.

A coordinate covalent bond could be formed between?
NH\(_{3}\) and PCl\(_{3}\)
BCl\(_{3}\) and AlCl\(_{3}\)
BCl\(_{3}\) and NH\(_{3}\)
H\(^{+}\) and AlCl\(_{3}\)
Correct answer is C
A coordinate covalent bond, also known as a dative bond, dipolar bond, or coordinate bond is a kind of two-center, two-electron covalent bond in which the two electrons derive from the same atom.
