Why is glucose named glucose?

mars1129 [50]

Answer:

Word that comes from a Greek word

Explanation:

Glucose is a natural monosaccharide, which has the following molecular formula: C6H12O6

From the chemical point of view, this molecule is a hexose (this is, it has 6 carbon atoms) and an aldose (since it has an aldehyde group)

Glucose as a word has its origin from the Greek word “gleukos”, which means “sweet wine”, and the suffix “ose”, which is used to for a sugar

French people then adapted this word (in order to define a new chemical word, to differentiate the type of sugar found in grapes, slight different from sugar found in other elements such as honey)

Draw a lewis structure for ketene, c2h2o, which has a carbon–carbon double bond

MrMuchimi

Visual representation of covalent bonding indicating the valence shell electrons in the molecule, lines represents the shared pair of electron and pair of electrons that are not involved in bonding are represented as dots(lone pairs) are known as Lewis structures.

Compound formation takes place in order to complete the octet of each element that is according to octet rule, each atom forms bond with other atom in order to complete their octet that is to get eight electrons in its valence shell and attain stability.

An organic compound of the form $R^{'}R^{''}C=C=O$ is known as ketene.

The given ketene is $C_2H_2O$ .

The number of valence electron of:

$C = 4$

$H = 1$

$O = 6$

The number of valence electrons in $C_2H_2O$ = $2\times 4+2\times 1+1\times 6 =16$

2 electrons are involved in each single bond between carbon and hydrogen and 4 electrons are involved in each double bond formed between carbon-carbon and carbon-oxygen. Hence, the total number of electrons involved in bond formation are 12 and rest 2 pair of electrons are present on oxygen as lone pair of electrons.

Therefore, the attached image is the Lewis structure of $C_2H_2O$ .
