The reaction proceeds through nucleophilic acyl substitution reaction.
Phenyl magnesium bromide substitutes one ethoxide ion in the nucleophilic acyl substitution reaction that drives the process forward. A subsequent equivalent of phenyl magnesium bromide produces triphenyl methanol through a nucleophilic addition reaction with the resultant keto group.
There are two ethoxy leaving groups in diethyl carbonate. Tertiary alcohol is created when diethyl carbonate combines with too much Grignard reagent. The Grignard reagent attacks the carbonyl carbon three times in the mechanism to produce the tertiary alcohol.
The mechanism is shown below:

Answer:
C5H6O3
Explanation:
Number of moles of hydrogen = 0.142 * 2 /18 = 0.0158 moles of H
Number of moles of carbon = 0.579 * 1/44 = 0.013 moles of C
Mass of C = 0.013 moles of C * 12 = 0.156 g
Mass of H = 0.0158 moles of H * 1 = 0.0158 g
Mass of oxygen = 0.3000 - (0.156 + 0.0158 )
Mass of oxygen = 0.1282 g
Number of moles of oxygen = 0.1282 g/16 g/mol = 0.008 moles of O
Dividing through by the lowest number of moles
C-0.013/0.008 , H- 0.0158 /0.008 , O- 0.008/0.008
1.625, 1.975, 1 (multiply through by 3)
5, 6, 3
The required empirical formula is C5H6O3
Answer:
C. aluminum, fluorine, silicon
The principle of radiation protection is to trigger deterministic and stochastic effect.
Explanation:
The main aim of principle of radiation is to prevent the deterministic effects of radiation and reduce the risks of stochastic effects.
There are three general principals of radiation used for dealing with ionising radiation are Justification, Dose limitation and Optimization.
The three basic radiation principles are time, distance and shielding.
The risk of exposure to radiation is measured using the conventional unit rem or SI unit (sievert).
