Consider the atom with the chemical symbol Ru.

Chemistry
1 answer:
Vinil7 [7]2 years ago
4 0

Answer: 97

Explanation:

The element Ru is <u>Ruthenium</u> which has <u>44 protons</u>.

In this case, our atom is an isotope with <u>53 neutrons</u>.

With this information, we can use the mass number formula to find this atom's mass number.

mass number = protons + neutrons

mass number = <u>44 protons</u> + <u>53 neutrons</u>

mass number = <u>97</u>

Question : The above compound is an ether. Give thestructure
Sphinxa [80]

Answer:

The above compound is an ether. Give thestructure  of the product(s) and indicate the major mechanism of the reaction  (SN1, SN2, E1 or E2). Indicate stereochemistry when necessary.

The mechanism that explains this transformation begins with the protonation of the  ether, which allows the subsequent SN2 attack of the iodide ion. This reaction forms  ethyl iodide and ethanol, which is also converted to ethyl iodide by reaction  with excess HI.

Explanation:

The SN2 reaction (also known as bimolecular nucleophilic substitution or as an attack from the front) is a type of nucleophilic substitution, where a pair of free electrons from a nucleophile attacks an electrophilic center and binds to it, expelling another group called the leaving group. Consequently, the incoming group replaces the outgoing group in one stage. Since the two reactant species are involved in this slow limiting stage of the chemical reaction, this leads to the name bimolecular nucleophilic substitution, or SN2. Among inorganic chemicals, the SN2 reaction is often known as the exchange mechanism.
