Nature of covalent and dative covalent bonds

Question 1

Single covalent bond contains…

Answer 1

shared pair of electrons

Question 2

Multiple bonds contain…

Answer 2

multiple pairs of electrons

Question 3

Dative covalent bond contains…

Answer 3

shared pair of electrons with both electrons supplied by one atom
- atom that is donating electrons has a pair not being used called the lone pair

Question 4

Properties of Covalent Bonding

Answer 4

• Weak attraction between molecules so not much energy required to break
• Poor conductors because molecules are neutral overall. (no charged particles to carry current)

Question 5

covalent bonding occurs between…

Answer 5

pair of non-metals

Question 6

Double covalent bonds

Answer 6

• 4 electrons shared

- 2 atoms in oxygen molecule share two pairs of electrons so oxygen has double bond
