Question

question 5 (1 point)
in biochemistry, nitrogen typically forms
4 bonds
2 bonds
3 bonds
5 bonds
question 6 (1 point)
polar molecules
are hydrophilic.
have low or no solubility in water.
occur when atoms share electrons.
have weak intermolecular forces.

Explanation:

• For Question 5: Nitrogen has 5 valence electrons. To achieve an octet (8 - electron configuration), it typically forms 3 covalent bonds.
• For Question 6: Polar molecules have a partial positive and partial negative end due to unequal electron - sharing (a type of covalent bond where atoms share electrons). They are hydrophilic (water - loving) and have relatively strong intermolecular forces (dipole - dipole forces). Non - polar molecules have low or no solubility in water.

Answer:

• Question 5: 3 bonds
• Question 6: occur when atoms share electrons.
