Answer:
The correct answer is - a. Fluorine is the leaving group in Sarin.
Explanation:
A leaving group is a group that leaves a complete negative charge in heterolytic cleavage when it separates out from the molecule. Sarine reacts with the active site of the enzyme acetylcholinesterase that is essential for nerve transmission.
In this given case, Sarin that is an acid fluoride and ester of methyl phosphonic acid, the fluorine atom is present is the one that leaves with a complete negative charge, therefore, fluorine is the leaving group in Sarin.
Thus, the first option is correct that Fluorine is the leaving group in Sarin.
Answer:
10 electrons will be present in an O2-
Explanation:
The atomic nucleus of oxygen contains 8protons and 8 neutron. It ionizes by gaining two more electrons making the total number of electrons in a doubly ionized oxygen to be 10 electrons.
The segment that represents melting is time (minutes) and temperature.
Answer A. The electronegativity of one atom is less than 1.7
Answer:
For most of its active life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space. At the end of a star's lifetime, its core becomes a stellar remnant : a white dwarf , a neutron star , or, if it is sufficiently massive, a black hole .
