Chemistry

mojhsa [17]3 years ago

Answer:

Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. The exact speed of sound in steel is 5,960 meters per second (13,332 mph)! But, this is only for the majority of solids. The speed of sound in all solids are not faster than in all liquids.

Answer:

THE SOUND TRAVELS FASTER IN SOLIDS BECAUSE ITS MOLECULES ARE CLOSE TO EACH OTHER WHILE LIQUIDS MOLECULES ARE NOT TIGHT AS OF SOLID AND IN GAS THE MOLECULES ARE FREE

Answer:

3rd option. 1–butanamine

Explanation:

To name the compound above, the following must be observed:

1. Locate the functional group in the chain. In this case the functional group is amine.

2. Locate the longest continuous carbon chain. This gives the parent name of the compound. In this case, the longest chain has 4 carbon i.e butane.

3. Since the functional group is amine, the parent name becomes butanamine i.e replacing the –e at the end in butane with –amine

4. Indicate the position of the functional group in the chain. In this case the functional group is at carbon 1

5. Name the compound by putting the above together.

The name of the compound is:

1–butanamine or butan–1–amine

Write the structure of a D-aldohexose that gives a meso compound on treatment with NaBH4 in water.
soldier1979 [14.2K]

Explanation:

Meso compounds are optically inactive stereoisomers. Despite of having chiral carbon, they do not show  optical activity because it has a plane of symmetry in its structure itself. It is superposable on its mirror image.

Aldo sugars on reaction which reducing agents such as , NaBH₄ reduces the carbonyl group in the sugar to alcohol and gives corresponding alditol.

<u>The D- aldohexose which on reduction gives a meso alditol are allose and galactose. </u>

<u>The structure is shown in the image below. Thus, in allitol and galactitol formed have internal plane of symmetry which makes the optically inactive.</u>
