Hexane would have the higher boiling point, due to the fact it's unbranched unlike 1,3-dimethlybutane, hexane would have more surface contact and hence more London forces acting upon it. As a result it wo...

Heat the oil up until it is a vapour Pass into fractionating column Negative temperature gradientHydrocarbons of different lengths have different boiling points They condense at different heights and are ...

A burrette is a measuring apparatus a burrette measures the volume of liquid delivered during a titration. with each measurement there is an uncertainty with the recorded measurement of delivered liquid. ...

Tetrahedral because there are 4 areas of electron density around the central carbon atom that repel as far away as possible. The bond angle is 109 degrees

Hydrogen bonding is a relatively strong inter-molecular force, caused by strong dipole-dipole interactions between an electron-deficient H atom and a lone pair of electrons...
