Explanation

An electrophile is a species that seeks electrons and can accept an electron pair.

C₂H₅OCH₃ (Ethyl methyl ether) is not an electrophile.

Because it lacks an electron-deficient center and does not readily accept electron pairs.

Explanation

The coordination number of the metal in [Cu(EDTA)]²⁻ is six because EDTA (Ethylenediaminetetraacetate) is a hexadentate ligand.

This meaning it can bind to the metal ion through six donor atoms.

Explanation

A mass spectrometer measures the mass-to-charge ratio (m/z) of ions.

It helps identify compounds based on their mass and fragmentation pattern.

Explanation

The magnetic moment (μ) is related to the number of unpaired electrons (n) by the formula:

μ = √(n(n+2)) BM

Given μ = 5.92 BM, we can solve for n:

5.92 = √(n(n+2))

n(n+2) ≈ 35.25

n ≈ 5

Explanation

Graphite is used in nuclear reactors as a neutron moderator.

It slows down high-energy neutrons to thermal energies to maintain the chain reaction efficiently.
