1 answer:
Citrus2011 [14]3 years ago
7 0

Answer:

E - Atomic mass is calculated by weighted atomic average using all the isotope data available.

G - Mass number is equal to the sum of protons and electrons in an atom.

Explanation:

Take an element

\\ \bull\sf\longmapsto _{25}Mg^{12}

  • Mass no is 25 and atomic no is 12.

Methylcyclopentene reacting with reacting with sulfuric acid and water
dlinn [17]

Answer:

The product is 1-methylcyclopentanol  

Explanation:

The acid-catalyzed hydration of alkenes involves the addition of a water molecule to a C=C double bond.

H₂O + C=C ⟶ H-C-C-OH

An H atom adds to one of the C atoms, and an OH group adds to the other

This reaction follows Markovnikov’s rule — the H adds to the C atom that has more hydrogen atoms, and the OH adds to the more substituted carbon.

The steps of the mechanism are:

  1. The aqueous sulfuric acid generates hydronium ions
  2. The nucleophilic π electrons attack an H atom  on the hydronium ion, forming a carbocation on the more substituted C atom.
  3. The lone pair electrons on a water molecule attack the carbocation , forming an oxonium ion.
  4. Another water molecule removes the extra proton.

The product is the alcohol with the OH group on the more substituted carbon — 1-methylcyclopentanol.
