The answer is true. Amorphous solids, also known as non-crystalline solid, lacks a long-range order seen in a crystalline solid. Examples are glass. polymers and silicon. Many solids around are in an amorphous form.

Answer:

True

Explanation:

Amorphous solid is the designation given to a structure that has no long-range (atomic) spatial ordering, such as regular solids. For a material to be considered as regular solid it must have a defined crystalline structure, which corresponds to a positioning of the atoms that compose it. Amorphous materials have no definite geometric shape, may even have some rigidity like ordinary solids, but their atoms are not in spatial organization (at the microscopic level), in which case amorphous solids have no general order, with individual clusters joined together only. by the forces of Van der Waals.

Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins. Note that

adelina 88 [10]

Answer:

The three-step synthesis of trans-2-pentene from acetylene is as follows.

Step -1: Formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkanes.

Step -2: Formation terminal alkyne to nonterminal alkynes.

Step -3: Formation of trans-pent - 2-pent-ene by reduction.

Explanation:

Synthesis of trans-pent-2-yne from ethyne takes place is mainly a three step synthesis which involves formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkane. Second step involves the further alkylation of terminal alkynes to higher order nonterminal alkynes and the third step involves the formation of trans-2-ene by dissolving reduction method.

The chemical reaction of each step of chemical reactions is as follows.
