Question

In each of the following (Carbon, hydrogen, nitrogen, oxygen), the maximum number of covalent bonds which can be formed is equal to the number of electrons needed to complete the outer shell. A) True B) False

THe higher the PH, the greater the acidity of a solution. A) True B) False

The chemical fusion of monomers into polymer chains is accomplished by A))addition of water and formation of ionic bonds between monomers B)addition of water and breaking of covalent bonds between monomers C)removal of water and formation of covalent bonds between monomers D)ionization of monomers in a nonpolar solvent E)hydrogen bonding of monomers with moelecules in a polat solvent

Which of the following would be typical of fibrous proteins rather than globular proteins? A)polypeptides folded into compact three dimensiaonl conformations B)include the greatest variety of proteins C)folding determined by tertiary structure as well of secondary structure D)properties more likely determined by secondary structure (alpha-helix and beta-sheet) E)contain a sugar phosphate backbone

Explanation / Answer

1. False. It involves the sharing of electron pairs between atoms.

2. False. If increase in PH it moves to alkaline PH>7

3. Removal of water and formation of covalent bonds between monomers. Dehydration take place.

4. Properties more likely determined by secondary structure
