Which statement describes solstices?

RSB [31]

Answer:

Option A (They happen as the Sun hits its maximum and minimum level throughout the sky) is the correct option.

Explanation:

Solstice seems to be the moment whereas at noon this same sun achieved its maximum as well as minimum position, actually results throughout the year's shortest as well as biggest days.
We currently believe that perhaps the solstice seems to be an apocalyptic event, exacerbated either by the tilt of the globe’s axis and therefore its direction of movement in an elliptical orbit. Globe's rotation not everyone's travel time from either the sun was what was causing winter or even just summer.

Some other options given should not be in accordance with the given context. So, the correct approach would've been option A.

Draw a structural formula of an alkene or alkenes (if more than one) that undergo acid-catalyzed hydration and without rearrange

lara31 [8.8K]

Answer:

-) 2-methylbut-2-ene

-) 2-methylbut-1-ene

-) 3-methylbut-1-ene

Explanation:

in this case, the hydration of alkenes is a marknovnikov reaction, this means that the "OH" group would be added in the most substituted carbon of the double bond. (Figure 1)

For 2-methylbut-2-ene the most substituted carbon is the tertiary carbon (the carbon in the right of the double bond), so we will obtain the desired molecule. In 2-methylbut-1-ene the most substituted carbon is again the tertiary carbon (the carbon in the bottom of the double bond), so we will obtain 2-methyl-2-butanol. Finally, for 3-methylbut-1-ene the carbocation would be formed on carbon 3, this is a secondary carbocation. We can obtain a most stable carbocation if we do a hydride shift (Figure 2). With this new molecule is possible to obtain 3-methylbut-1-ene.
