What do sedimentary rock layers reveal about ancient environments?

1 answer:

8 0

The most comprehensive story of ancient environment is traced by type of Sedimentary rocks. The different ancient environment forms different kinds of sedimentary rocks in terms of shape, size, pattern of sorting etc.

For example:

an ancient environment of lake will have laminated sedimentary rocks while a deserted one will have cross beds or granules.

Not only this we can also have an idea about the kind of flora and fauna of ancient environment based on the fossils. which may be in the form of architectural features.

So they reveal both kind of life / living organism and the kind of earth like river, desert, lake, swamp, lagoon etc.

P-fluoroanisole reacts with sulfur trioxide and sulfuric acid. Draw the major product of this substitution reaction; if applicab

Ipatiy [6.2K]

Answer: (Structure attached).

Explanation:

This type of reaction is an aromatic electrophilic substitution. The overall reaction is the replacement of a proton (H +) with an electrophile (E +) in the aromatic ring.

The aromatic ring in p-fluoroanisole has two sustituents, an halogen and a methoxy group, which are ortho-para directing substituents.

Aryl sulfonic acids are easily synthesized by an electrophilic substitution reaction aromatic using sulfur trioxide as an electrophile (very reactive).

The reaction occurs in three steps:

The attack on the electrophile forms the sigma complex.
The loss of a proton regenerates an aromatic ring.
The sulfonate group can be protonated in the presence of a strong acid (H₂SO₄).

Normally, a mixture of ortho-para substituted products would be obtained. However, since both para positions are occupied, only the ortho substituted product is obtained here.
