What is metamerism with example?

Metamerism is the repetition of homologous body segments. This type of development can be seen in the Annelids, which include earthworms, leeches, tubeworms, and their relatives. The earthworm is an example of an annelid showing true metamerism.

What is metamerism in structural isomerism?

Metamerism is a type of structural isomerism in which different alkyl groups are attached to the same functional group. For example, diethyl ether and methyl propyl ethers are metamers.

What is metamerism 11th class?

Answer: (b) Metamerism is the division of animal body, externally and internally into segments with a serial repetition of at least some organism, e.g., annelids (earthworm). However, Segmentation refers to the division of animal’s body into a series of repetitive segments.

What is metamerism in chemistry class 12?

Solution 2. Metamerism (positional isomerism): Ethers having same molecular formula but different alkyl groups attached on either side of the oxygen atom are called metamers of each other. This phenomenon is called metamerism (positional isomerism).

What is metamerism and Tagmatization?

Metamerism produces specialization in regions of the body for specific functions. The regional specialization is called tagmatizafion. In arthropods,, body regions are called tagmata, tagmata are specialized for feeding and sensors perception, locomotion and visceral functions.

What does Metamere mean?

Definition of metamere : any of a linear series of primitively similar segments into which the body of a higher invertebrate or vertebrate is divisible.

What is metamerism in BYJU’s?

It is a type of isomerism in which compounds having the same molecular formula but different alkyl groups on either side of functional groups are called Metamerism.

What is metamerism Ncert?

Metamerism is the phenomenon of forming a linear series of body segments that are similar in structure. A metameric segment is also called as somite.

What is metamerism BYJU’s?

Metamerism is a type of segmentation where the body is divided externally and internally into segments with linear repetition of organs in each segment. This is a characteristic feature of earthworm, leech and Nereis, which belong to phylum Annelida.

What is ring chain isomerism?

Ring-chain isomerism is a process which involves the transformation of molecule from an open-chain structure into a ring structure. 1 Such isomerization is classified into valence isomerism and additive isomerism.

What do you mean by metamerism?

It is a type of isomerism in which compounds having the same molecular formula but different alkyl groups on either side of functional groups are called Metamerism Example diethyl ether and methyl propyl ethers are metamers. Was this answer helpful? 2.5 (23) (26)

What is Metamerism and tautomerism?

Define metamerism and tautomerism. Metamerism: Compounds having the same molecular formula but a different number of carbon atoms (or alkyl groups) on either side of the functional group (i.e.– O –, – S – CO – NH–) are called metamers and the phenomenon is called metamerism.

What is Metamerism and how does it differ from chain isomerism?

Metamerism is one among the five types (Chain isomerism, positional isomerism, functional isomerism, metamerism and tautomerism)of structural isomerism exhibited by the organic compounds. They have the same molecular formula and functional group but differ in the alkyl group present on both the sides of the functional group.

What are metamers in organic chemistry?

Metamers are isomers which differs by the structural carbon atoms distribution at the sides of a polivalent functional group. As such given a linear chain they are positional isomers too, with respect to the position of the polivalent functional group.
