How could the following compounds be synthesized from acetylene? Compound a is CH3CH2CH2CCH, with a triple bond between the fourth (from left to right) and the fifth carbons. Compound b is CH3CHCH2, with a double bond between the second (from left to right) and the third carbons. Compound c has a structure of a CC double bond in its structure, with a CH3 group attached to both carbons above and an H atom attached to both carbons below the double bond. Compound d is CH3CH2CH2CH2CH, with an O atom double-bonded to the fifth (from left to right) carbon. Compound e is CH3CHCH3, with a Br atom attached to the second carbon. Compound f is CH3CCH3, with two Cl atoms attached to the second carbon. Complete the syntheses by dragging the labels to the appropriate targets.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
