small covalent molecules

Question 1

simple molecular substances have ___ melting and boiling points?

Answer 1

simple molecular substances have low melting and boiling points

Question 2

simple molecular substances are usually ____ or ____ at room temperature?

Answer 2

simple molecular substances are usually gases or liquids at room temperature

Question 3

why are melting and boiling points of simple molecular substances low?

Answer 3

because we are not breaking the covalent bonds, we are breaking the weak intermolecular forces

Question 4

are covalent bonds broken when a substance melts or boils?

Answer 4

no

Question 5

as we increase the size of the covalent molecule, intermolecular forces ____?

Answer 5

as we increase size of covalent molecule, intermolecular forces increase

Question 6

do small covalent molecules conduct electricity?

Answer 6

no

Question 7

why dont small covalent molecules conduct electricity?

Answer 7
