An element contains covalent bonding and London dispersion forces - Scottish Highers Chemistry - Question 5 - 2018
Question 5
An element contains covalent bonding and London dispersion forces. The element could be A boron B neon C sodium D sulfur.
Worked Solution & Example Answer:An element contains covalent bonding and London dispersion forces - Scottish Highers Chemistry - Question 5 - 2018
Step 1
The element could be D sulfur.
Answer
To determine which element contains covalent bonding and London dispersion forces, we analyze each option:
-
A: Boron – Boron can form covalent bonds; however, it typically exhibits covalent bonding without significant London dispersion forces in its elemental state.
-
B: Neon – Neon is a noble gas and does not form covalent bonds; it primarily exhibits London dispersion forces but not covalent bonding.
-
C: Sodium – Sodium typically forms ionic bonds rather than covalent bonds, eliminating it as a candidate.
-
D: Sulfur – Sulfur is known to form covalent bonds when it combines with other nonmetals and also exhibits London dispersion forces due to its larger size and presence of electrons.
Given that sulfur is the only option that encompasses both covalent bonding and London dispersion forces, the answer is D sulfur.
