Answer:
D) will not form any stereoisomers since the product is a saturated hydrocarbon.
Explanation:
Stereoisomerism, or spatial isomerism,refers to a type of isomerism in which two or more molecules have the same molecular formula and atom to atom connectivity but different three-dimensional orientations of those atoms in space.
Stereoisomerism occurs in alkenes because free rotation about the C=C bond is hindered. Thus, the molecule is "locked" in a particular orientation. In a saturated alkane, there is unrestricted free rotation about the C-C bond hence straight chain alkanes do not have steroisomers.
The product formed is 3,4-dimethyl hexane which is a straight chain saturated alkane. This compound does not exhibit stereoisomerism.
I'm assuming you need to know the percentage yield of the reaction
To calculate the percentage yield = (actual yield x 100%) / predicted yield
actual yield is 56,9 g
predicted yield is 36,6g ( is the amount that's expected if nothing had got lost)
(56,9 x100)/36,6=
= 155%
What does it happen in smallest scale?
<span>You have to look for "DUPRE' EQUATION" which treat about </span>
<span>"TWO-PHASE INTERFACIAL FORCEs". </span>
<span>At boundary surface between two aggregation phases, you may attribute upper energy level to molecules standing at the boundary zone. So, it has to define INTERFACIAL FORCEs WHICH ACT TO REMODEL SHAPE AND EXTENSION OF MEETING PHASEs. </span>
<span>In your case, Water's Droplet is a liquid phase surrounded by Air (e.g. gas phase) and Interfacial Forces act to dominate Boundary-Surface. </span>
<span>Mathematically, smallest possible Surface comes to SPHERICAL SHAPE. </span>
Answer:
22)convex
23)sun (sunlight reflect of the off the surface of the moon
24)because of the way the atmosphere interacts with sunlight
25) transparent : glass,contact lenses,water,air
translucent: wax paper, oil paper, thin sheets
opaque : plastic, wood, leather
26)when light react with opaque: none of it passes though
when it reacts with transparent : it passes through
when it react with translucent : only some of it passes through, the light does not pass directly through the material
Explanation:
24 blue light is scattered in all directions by the tiny molecules of air in earth's atmosphere
