How do i know what the major and minor products of the reaction between Hydrogen Bromide and Propene would be?

We would use something called Markovniov's rule. Essentially, the H+ ion (or proton) that is attracted to the electron dense double bond of the alkene, is added to the carbon that has the most Hydrogen at...

Order the following in terms of boiling point and explain your reasoning: Ethanol, Ethane, Propane

All three molecules have induced dipole-dipole interactions. Propane has a higher boiling point than ethane as propane has a higher molecular mass. This means there are more electrons present and the indu...
