Why is an amide less reactive to nucleophilic acyl substitution than an acid chloride?
Olin [163]

An amide is less reactive to nucleophilic acyl substitution than an acid chloride because more electron density is donated to the carbonyl by nitrogen.

<h3>What is electron density?</h3>

In quantum chemistry, electron density, also known as electronic density, is a metric for the likelihood that an electron will be found at a microscopic portion of space surrounding a specific point. The likelihood of finding an electron at a particular position near an atom or molecule is represented by electron density. In general, areas with a high electron density are where the electron is most likely to be located. The attractive forces between the electrons and the nuclei in a molecule are what hold the nuclei together in molecule, hence the electron density is essential to the bonding and geometry of a molecule. The repulsions between the nuclei and the electrons function as an antagonist to these attractive forces.

10. Which of the following mirror is used to form smaller image
vitfil [10]

Answer:

Correct answer is b) convex mirror

Explanation:

A convex mirror, which bulges outward, reflects at a wider angle near its edges than at its center, creating a slightly distorted image that's smaller than actual size. Convex mirrors have many uses. The smaller size of the images means that you can see more with these surfaces, hence their use in safety mirrors.

The isotopic mass of ²¹⁰₈₆Rn is 209.989669amu. When this nuclide decays by electron capture, it emits 2.368 MeV. What is the iso
zaharov [31]

Starting from the radon mass, add the mass of the electron, and subtract the mass attributable to the gamma radiation <u>(931 Mev = 1 amu).</u>

<h3>What is gamma radiation?</h3>

Gamma radiation (gamma rays) refers to the part of the electromagnetic spectrum with the most energy and shortest wavelength. Astrophysicists define gamma radiation as any radiation with an energy above 100 keV. Physicists define gamma radiation as high-energy photons released by nuclear decay.

Using the broader definition of gamma radiation, gamma rays are released by sources including gamma decay, lightning, solar flares, matter-antimatter annihilation, the interaction between cosmic rays and matter, and many astronomical sources. Gamma radiation was discovered by Paul Villard in 1900.

Gamma radiation is used to study the universe, treat gemstones, scan containers, sterilize foods and equipment, diagnose medical conditions, and treat some forms of cancer.
