Actually the answe is mass.
Answer:
Four products are possible.(in attachment)
2,3,4,5 carbons attached to the bromine.
Explanation:
NBS is N-bromosuccinamide which is used to brominate the allylic and benzylic positions of the compound.
Mainly used for the allylic bromination Here, four products are possible among them two are formed by the direct allylic bromination and remaining two products are formed by the rearrangement of the radical formation.
2,3,4,5 carbons of the compound are attached to the bromine.
Multiply 3 by the atomic mass of fluorine, forgive me if I’m wrong
Answer:
Option C:- Concentration
Explanation:
Coal dust explosion can cause lots of damage. To avoid
this, the amount or concentration of coal dust per unit
volume or MEC is measured with the various conditions
of coal storage such as the particle size, moisture of coal,
degree of dispersion and delayed time of ignition source
to prevent the coal dust explosion which aims to study
and design the explosion safety measures for coal dust
handing installations. The results present that moisture
content in coal has more effect on dust explosion. The
smaller size of particle, low moisture in coal and high
coal dust dispersion can increase the possibility or risk of
dust explosion.
Alkyl halide, Isobutylene
