Answer:
<u>Metalloid -</u>
A metalloid is a chemical element with properties intermediate between those of typical metals and nonmetals
<u>Alloy</u> -
An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by a metallic bonding character.
The volume of the snow decreases. This had happened because the
snow is made up or comprised of water (H2O) and oxygen (O). When the snow starts
melting, the air inside the snow discharges into the atmosphere and the water turn
out to be a puddle on the ground.
We have to draw the structural formula of trans-1-bromo-3-isopropylcyclobutane.
The structure is shown below in Figure1.
The molecule trans-1-bromo-3-isopropylcyclobutane has four atoms in the skeleton and Br atom is attached at 1 position and isopropyl group at 3-position.
Trans structure means both groups are in opposite directions.
The trend of atomic radius in the periodic table is increasing from right to left and from top to bottom. In reference to the table, oxygen has smaller radius compared to carbon, which is smaller than aluminum and which is also smaller than potassium. Thus, the trend from smallest to biggest is oxygen carbon, aluminum and potassium.
Answer:
3,5-dimethyl-2-octene
Explanation:
Please note that there is no H at carbon 3 less carbon becomes penta hydra.
The compound is:
CH3
I
C = CH2 - CH3
I
CH2
I
CH - CH3
I
CH2
I
CH2
I
CH3
To name the above compound, do the following:
1. Locate the longest continuous chain i.e octene
2. Start counting from the side that gives the double bond the lowest low count since the double bond is the functional group. In doing this, the double bond is at carbon 2.
3. Locate the substituent groups attached and their position in the parent chain. In doing so, you will see that there are two CH3 group attached and they are at carbon 3 and carbon 5. Since the substituents attached are the same, we'll name them as 'dimethyl' indicate that they are two methyl groups
Now, we'll combine the above findings in order to obtain the name. Therefore, the name of the compound is:
3,5-dimethyl-2-octene
