Sugars are technically called carbohydra...

Sugars are technically called carbohydrates, referring to the fact that their formulae are only multiple of `Cn(H_(2)O)n`. Hexoses therefore have six carbons, twelve hydrogens and six oxygen atoms. Glucose is a hexose. Choose from among the following another hexose.

A

Fructose

B

Erythrose

C

Ribulose

D

Ribose

The correct Answer is:
To solve the question, we need to identify another hexose sugar besides glucose. Hexoses are carbohydrates that contain six carbon atoms, and their general formula is C6H12O6. ### Step-by-Step Solution: 1. **Understanding Hexoses**: - Hexoses are monosaccharides with six carbon atoms. Their molecular formula is Cn(H2O)n, where n=6 for hexoses, resulting in the formula C6H12O6. 2. **Identifying Glucose**: - The question states that glucose is a hexose. Glucose has the formula C6H12O6. 3. **Finding Another Hexose**: - We need to find another sugar that also has the formula C6H12O6. Common hexoses include glucose, fructose, and galactose. 4. **Evaluating Options**: - If the options provided include fructose, we can confirm that fructose is also a hexose, as it has the same molecular formula (C6H12O6) as glucose. 5. **Conclusion**: - Therefore, another hexose besides glucose is fructose. ### Final Answer: Another hexose is **fructose**.

Nitrogen , oxygen and fluorine are the highly electronegative elements. When they are tied to a hydrogen atom to form covalent bond, the electrons of the covalent bond are shifted towards the more electronegative atom.This partially positively charged hydrogen atom forms a bond with the other electronegative atom. This bond is called as hydrogen bond and is weaker than covalent bond.For example, in HF molecule, the hydrogen bond exists between hydrogen atom of one molecule and fluorine atom of another molecule as depicted ---H^(delta+)-F^(delta-)---H^(delta+)-F^(delta-)---H^(delta+)-F^(delta-) Here, hydrogen bond acts as bridge between atoms which holds one atom by covalent bond and the other by hydrogen bond.Hydrogen bond is represented by a dotted line (---) while a solid line represents the covalent bond. Thus, hydrogen bond can be defined as the attractive force which binds hydrogen atom of one molecule with the electronegative atom (F,O and N) of another molecule.

Q. Among molecules of HCl, which of the following forces are present.

Borane is an electron deficient compound. It has only six valence eletons, so the boron atom lacks an octet. Acquiring an octet is the driving force for the unusual bonding structure found in boron compounds. As an electron deficient compound, BH_(3) is a strong electrophile, capable of adding to a double bond. This hydroboration of double bond is though to oC Cur in one step, with the boron atom adding to the less highly substituted end of the double bond. In transition state, the boron atom withdraws electrons from the pi bond and the carbon at theother end of the double bond acquires a partial positive charge. This positive charge is more stable on the more highly subsituted carbon atom. The second step is the oxidation of boron atom, removing it from carbon and replacing it with hydroxyl group by using H_(2)O_(2)//OH^(bar(..)) . The simultaneous addition of boron and hydrogen to the double bond leads to a syn addition. Oxidation of the trialkyl borane replaces boron with a hydroxyl group in the same stereochemical position. Thus, hydroboration of alkenen is an example of steropecific reaction, in which different steroisomers of starting compounds react to give different steroisomers of the product.
