Which compound is a member of the same homologous series as 1-chloropropane? A. 1-chloropropene B. 1-chlorobutane C. 1-bromopropane D. 1,1-dichloropropane

It's B. Chlorobutane

In explaining this answer, I'd test the students knowledge of what a homologous series is. And then we'd draw out the alternative answers and I'd ask the student to explain why...

Sodium and sodium iodide can both conduct electricity when molten, but only sodium can conduct electricity when solid. Explain this difference in conductivity in terms of the structures of sodium and sodium iodide.

When approaching a question like this, it’s important to identify the two compounds that we are dealing with first. Sodium is an alkali metal, and therefore the metallic structure that it forms comes from...

Cu2+ (aq) reacts with ammonia to form the complex ion [Cu(NH)3)4]2+. Explain this reaction in terms of acid-base theory, and outline the bonding in the complex formed between Cu2+ and NH3

Ammonia acts as the Lewis base in this reaction by donating its lone pair of electrons, whilst Cu2+ (which is an electron deficient, electrophile) accepts the lone pair of electrons from the ammonia, maki...
