What sort of nucleophile does NADH supply?
Elden [556K]

Answer:

Hydride ion

Explanation:

You often see the reduction with NADH written as

NADH ⟶ NAD⁺ + H⁺ + 2e⁻

If you think about it, H⁺ + 2e⁻ is equivalent to H:⁻, so we could write the reaction as

NADH ⟶ NAD⁺ + H:⁻

In terms of a mechanism, the dihydropyridine ring of NADH transfers a hydrogen atom with its pair of electrons (a hydride ion) to the substrate and becomes the more stable, aromatic pyridinium ion in NAD⁺.

How many grams in 2.75L of CL
Tamiku [17]

mass of Cl₂ = 8.61 grams

Explanation:

We have 2.75 of chlorine (Cl₂) which is gas. If we assume that it is behaving like an ideal gas and we work under standard conditions, we can use the following equation.

number of moles = volume / 22.4 (L / mole)

number of moles of Cl₂ = 2.75 / 22.4 = 0.123 moles

number of moles = mass / molecular weight

mass = number of moles × molecular weight

mass of Cl₂ = 0.123 × 71 = 8.61 grams
