### Naming with rings

When do you consider a ring a substituent versus the main carbon chain?

### Naming Substituents and Carbon Pair

When naming a hydrocarbon, do the numbers that represent what carbon the substituent is bonded to always start with the least carbon and the first named substituent or is it only when the substituent numbers are the same?
Hope I make sense!

### Molar Heat Capacity

Can the equation to find the heat required, (qp)=∆H=nCp∆T, still be used with a value for constant volume instead of pressure?

### Electron Configuration

When writing out the electron configuration, do we have to specify which p orbital (∏2Pz) or just indicate that it is in the p orbital (∏2P)?

### Polarity

In general, how do we determine polarity? I know this question is already posted but it really didn't help me.

Thank you

### Hydrocarbons and Combustion

When trying to find the empirical formula of a hydrocarbon that combust and produces CO2 and H2O we have to find the mass of carbon and hydrogen but when trying to find the mass of hydrogen in H2O do we use the ratio (1.008/18.015) or (2.016/18.015)?

Thank You

### Homework 2.29 - Atomic Orbitals and Electrons

The question asks how many electrons can have the following quantum numbers in an atom. A) n=2, l=1 This orbital is 2p and 6 electrons can have these values B) n=4, l=2 ml=-2 With n and l the orbital is 4d. I would assume that 10 electrons can have these values but the solution manual says two elect...
