Explanation:
Anisotropy is the property of being directionally dependent, which implies different properties in different directions, as opposed to isotropyAn example of anisotropy is light coming through a polarizer. Another is wood, which is easier to split along its grain than across it.
There are several differences between a physical and chemical change in matter or substances. A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.
Answer:
Route 1: In order to obtain 3‑methyl‑3‑pentanol, the reagent 1 should be ethyl acetate (ester) and the reagent 2 should be ethyl magnesium bromide (Grignard).
Route 2: In order to obtain 3‑methyl‑3‑pentanol, the reagent 1 should be 3-pentanone (ketone) and the reagent 2 should be methyl magnesium bromide (Grignard).
Explanation:
In planning a Grignard synthesis it is important to notice the groups attached to the carbon atom bearing the alcohol group.
For route 1 the reagent 1 is an ester thus, the R group chousen will be added twice because the first step form a ketone and the second step form the tertiary alcohol. To obtain 3‑methyl‑3‑pentanol the reagent 1 should be ethyl acetate and the reagent 2 should be ethyl magnesium bromide because of that the only possibility.
For route 2 the reagent 1 is a ketone so, only one R group will be added. One possibility is 3-pentanone as the ketone and methyl magnesium bromide as Grignard reagent.
Answer:
Proper names of ships and other vessels should be italicized just as titles are. Keep in mind that although ship (or vessel) names should appear in italics, prefixes such as U.S.S. or H.M.S. should not.
