The speed of a wave (c) is the product of its frequency (ν) and wavelength (λ). E = hv = h x c / λ nm to m or m to nm 1 m / 10^9 nm or 10^9 nm / 1 m What is the maximum number of electrons that can have the quantum numbers n = 3, ℓ = 2, mℓ = -2? The Pauli exclusion principle states that no two electrons in a given atom can share the same set of four quantum numbers (n, ℓ, mℓ, ms). This set of quantum numbers contains three quantum numbers, with the only missing quantum num...

OCR A LEVEL ORGANIC CHEMISTRY YEAR 12 WITH VERIFIED QUESTIONS AND ANSWERS What is the melting and boiling points of alkanes like? - ANSWER--as chain length increases so does the strength of the intermolecular forces as there is greater surface area for contact between molecules and hence stronger london forces and therefore the melting/boiling points are highr for longer chain. What is a structura/chain isomer? - ANSWER--Same molecular formula but a different structural formula Wh...
