The difference between an organ and a tissue is that basically tissues are a group of similar cells that works together. Then a group of tissue that works together would make up an organ. Groups of organ working together later makes up an organ system. This is the main difference between an organ and a tissue.

The difference is an organ system is made of a GROUP of ORGANS that are working to do a specific job while a organ is made up of a group of TISSUES, not group of organs, but tissues, to work in harmony to do a specific job. So basically the organ system is in its name, system of organs, so that helps u see that its a group of organs running together.

Which of the following bases is the STRONGEST? The base is followed by its Kb.A. C6H5NH2, 4.0 × 10-10 B. NH3, 1.76 × 10-5 C. CH3

Kamila [148]

Answer:

(D) (CH3CH2)2NH

Explanation:

In order to decide which base is strongest we need to calculate its PKb

PKb = -log [Kb]

A large Kb value and small PKb value gives the strongest base

Compound Kb PKb

(A) C6H5NH2 - 4 x 10^-10 9.349

(B) NH3 1.76x 10^-5 4.754

(D) (CH3CH2)2NH 8.6x 10^-4 3.066

(E) C5H5N 1.7x10^-9 8.77

Clearly (CH3CH2)2NH is the strongest base.

S-2-iodooctane lost his opticaly activity in soln on tratment wwithNaI. Explain

IceJOKER [234]

Answer:

Repeated SN2 reactions occur leading to the formation of a racemic mixture

Explanation:

S-2-iodooctane is a chiral alkyl halide with an asymmetric carbon atom. The presence of an asymmetric carbon atom implies that it can rotate plane polarized light and thus lead to optical isomerism. The two configurations of the compound are R/S according to the Cahn-Prelong-Ingold system.

However, when S-2-iodooctane is treated with sodium iodide in acetone, repeated SN2 reactions occur since the iodide ion is both a good nucleophile and a good leaving group. Hence a racemic modification is formed in the system with time hence we end up with (±)- Iodooctane.
