<span>I would say D because the Br is bonded to a tertiary carbon (a carbon bonded to three other carbon atoms). This makes the bond more stable compared to if the Br was bonded to a primary or secondary carbon, and so it is unlikely for spontaneous substitution of Br for OH to occur. Hydrolysis occurs through reaction intermediates that make the making and breaking of C-OH and C-Br bonds respectively more favourable.</span>
The correct answer for #8 is:
C. The original pattern of the light is distorted.
Answer:
Na2SO4
Explanation:
In the crisscross method, we can write the correct formula for an ionic compound by crossing over the numerical value of each of the ion charges to now serve as the subscript of the oppositely charged ion. Subsequently, the signs of the charges are dropped and the correct formula of the ionic substance is obtained.
For sodium sulphate;
Na ^+ SO4^2-
By crisscrossing and dropping the signs to obtain the subscripts we now have;
Na2SO4
