meso-2 , 3- Dibromobutane on debromination gives trans-2-butene.

What is obtained by Debromination of meso Dibromobutane?

Meso”2, 3″Dibromobutane on debromination gives trans”2″butane.

trans-2-butene.

What is meso Dibromobutane?

Meso dibromobutene is the bromination product of trans-2 butene so after debromination the same product is obtained.

Meso compounds are optically inactive due to internal compensation. Out of the given compounds only 2, 4-dibromopentane have a plane of symmetry, so it is a meso compound.

What is the structure of 2/3-Dibromobutane?

How many stereoisomers does 2/3-Dibromobutane have?

Because it has a meso form, 2,3-dibromobutane has only 3 unique stereoisomers.

Which is a meso compound?

A meso compound or meso isomer is a non-optically active member of a set of stereoisomers, at least two of which are optically active. This means that despite containing two or more stereogenic centers, the molecule is not chiral.

Which one of the following compound is optically active?

As per the definition, here we can see one carbon atom in Lactic acid is seen to be bonded to four different atoms or groups of atoms forming a Levo and a Dextro structure. Hence, Lactic acid is optically active in nature.

Which one of the following compound is least basic?

Aromatic amines are weaker bases than ammonia as well as aliphatic amines because the lone pair of electrons on the N atom is partly shared with the ring and is thus less available for sharing with a hydrogne ion .

Which one of the following compounds gives methane on treatment with water?

Al4C3.

Which of the following is meso 2 3 Dibromobutane?

How many stereoisomers does 2/3 Dichlorobutane have?

They are superimposable on each other, so they are the same compound. So, there are only three stereoisomers of 2,3-dichlorobutane.

How many isomers of the formula C4H8Br2 are there?

There are 9 structural isomers possible for this C4H8Br2.

How many enantiomers does 2/3 Dichloropentane have?

Earlier we looked at 2,3-dichloropentane and identified four stereoisomers (two pairs of enantiomers).

Does Meso 2/3-butanediol have an internal mirror plane?

(The word meso means “in the middle.”) Figure 6.14 A 180° internal rotation of (2R,3S)-2,3-butanediol gives an eclipsed conformation that is achiral because it has a plane of symmetry (internal mirror plane).

Which of the following compounds are not chiral 2 3 Dibromobutane?

Therefore, the answer to this question is option C, 3-dibromopentane.

What is meso compound give example?

Examples 1 and 2 are classified as meso compounds because they have at least two chiral centers and internal mirror planes, as indicated by the broken lines. In Example 3, hydrogen (H) and chlorine (Cl) are on the internal mirror plane, so Example 3 is still classified as a meso compound.

Which is a meso compound 2R 3r 2 3 Dibromobutane?

Which is a meso compound Mcq?

Which is a meso compound? Explanation: (2R,4S)-Dibromopentane is superimposable on its mirror image, so it is achiral (i.e., not chiral). Achiral molecules which have chirality centers are called meso compounds.

Is 4 hydroxy heptane optically active?

4-Hydroxyheptane has no chiral centra and is thus optically inactive.

Which of the following will have a meso isomer also?

2, 3 ” dichlorobutane.

Which compound is optically inactive?

A compound incapable of optical rotation is said to be optically inactive. All pure achiral compounds are optically inactive. eg: Chloroethane (1) is achiral and does not rotate the plane of plane-polarized light. Thus, 1 is optically inactive.

Which compound is most basic?

It is very much like a primary amine and lone pair of electrons on N are easily available. Hence, the most basic compound is Benzylamine and the correct option is D.

Which compound is least basic in structure?

NI3 is least basic because Iodine has vacant d orbital hence it can accept lone pair of electrons from Nitrogen and help in back bonding. Also, basicity decreases down the group and in this manner as well NI3 is less basic than any other given compounds.

Which amine is less basic?

Basicity of amines can be explained on the basis of availability of electron density on N-atom for protonation. Because of the +I effect, alkyl group increases the electron density on N-atom in alkyl amines. However, aniline is less basic because phenyl group exerts ‘I effect, ie, it withdraws electrons.
