Upon analysis, a hydrocarbon was found to contain82.8% carbon and 17.2%hydrogen. Calculate the empirical formula. 1.00g of hydrocarbon (as a gas) had a volume of 420mL at 1atm pressure and at 298K. Calculate the molecular weight and hence the molecular formula. Draw all possible structures for this compound and name them.

Label the discccaharides (Lactose, Maltose and Sucrose) as reducing and non-reducing and explain why you say so. Also briefly explain what will happen when Tollen’s reagent is added to each of the carbohydrates in an experimental condition.

Benzo[a]pyrene (B[a]P) is considered to be the most dangerous polycyclic hydrocarbon. Explain.

Explain why aniline does not undergo Friedel-Crafts reactions.

he serotonin reuptake protein transports the neurotransmitter from outside neurons into neurons. This happens against its concentration gradient, meaning that serotonin is pumped from an area of relatively low concentration to high concentration. The serotonin reuptake protein would therefore be a/an:

-ion channel.

-Carrier protein.

-Receptor.

-Enzyme.

-None of these options.
