Answer

Brief Explanations:

For Question 14: In molecular - structure determination, atoms are arranged around the least electronegative central atom. Electronegativity determines an atom's ability to attract electrons. For Question 15: A covalent bond is formed when atoms share a pair of electrons. Ionic bonds involve electron transfer, coordinate - ionic bonds are a special type of bonding, and hydrogen bonds are intermolecular forces.

Answer:

Question 14: C. electronegative Question 15: D. covalent bond
