Can two monosaccharides have the same formula yet have different structures?
yes they can it is known as isomerism and isomerism is two molecules can have the same formula but completely different structures
Why elctrovalent compound does not show the isomerism while covalent compound show isomerism?
Nt sure I agree with the question. Consider the octahedral polyatomic ion Co(NH3)4Cl2+ this has trans and cis isomers (chlorines opposite each other at 180 0 or next to each other at 90 0). Generelly isomerism is rare in electrovalent compounds. One interesting example is the optical isomerism of ammonium sodium tartrate discovered by Pasteur.
What is meant by isomerism and what are the types of isomerism?
Isomerism is the phenomenon in which two or more compounds have same molecular formula but their structural formula is different. The compounds are called Isomers.There are 2 types of isomerism.1) Structural Isomerism which is further classied into 5 more types of isomerisms:i) Chain Isomerism which is due to difference in nature or the carbon chain e.g. isopentane, neopentane or n-pentaneii) Position isomerism which is due to the difference in position of the functional group or unsaturated linkage in the same carbon chain. e.g. 1-Chloropropane is the isomer or 2-chloropropane or another example is 1-butene which is isomer of 2-buteneiii) Functional group isomerism in which there are different functional group but same molecular formula. e.g. dimethyl ether is functional group isomer of ethyl alcoholiv) Metamerism is due to the unequal distribution of carbon atoms on either side of the functional group and such compounds belong to same homologous series. e.g. diethyl ether and methyl n-propyl ether are metamers.dietheyl ether: CH3 - CH2 - O - CH2 - CH3methyl n-propyl: CH3 - O - CH2 - CH2 - CH3v) Tautomerism due to shifting of proton from one atom to other in the same molecule.The 2nd type of isomerism is Cis-trans Isomerism or geometric isomerism and compounds who possess same structural formula but differ with respect to the positions of the identical groups in space are called cis-trans isomers and the phenomenon is cis-trans or geometric isomerism.
Why does covalent compound exhibit isomerism?
They may have a same molecular formula, but different structures of bonding or differed spacial arrangement, and these are called isomers.
Why does a tetrahedral complex of the type MA2B2 not show geometrical isomerism?
For Geometrical isomerism the free rotation about the bonds should be restricted so a double bonded or cyclic compound may show the geometrical isomerism.

Which amino acid does not show any optical isomerism?
Glycine because it is not chiral :)

What is the another name of geometric isomers?
Geometric isomerism also known as cis-trans isomerism or E-Z isomerism
Is cis-trans isomerism included in geometrical isomerism?
The geometrical isomerism is mainly Cis-trans isomerism but in some cases we use another term Z and E isomers, they are almost same.
Why is isomerism not found in propane?
Isomerism is a phenomenon where compounds have the same chemical formula but different structural arrangements. Propane (C3H8) consists of three carbon atoms bonded in a straight chain with eight hydrogen atoms attached. Since there are no other possible ways to arrange the carbon atoms, propane does not exhibit isomerism.

What are stuctural isomerism?
Structural isomers are substances having the same formulas but different structures.

Does isomerism exist in disaccharides?
Yes
