Answer:
<u>It</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>combustion</u><u> </u><u>reaction</u><u>.</u>
Answer: Option (d) is the correct answer.
Explanation:
Steps involved for the given reaction will be as follows.
Step 1: (fast)
Rate expression for step 1 is as follows.
Rate = k
Step 2:
This step 2 is a slow step. Hence, it is a rate determining step.
Step 3. (fast)
Here, is intermediate in nature.
All the steps are bimolecular and it is a second order reaction. Also, there is no catalyst present in this reaction.
Thus, we can conclude that the statement step 1 is the rate determining step, concerning this mechanism is not directly supported by the information provided.
Answer:
HCl is a Bronsted acid, dissociates partially or completely with the release of H+ dissociating as H+ and Cl-.
BF_3 is a Lewis acid because it has an incomplete octet and an empty 2p orbital, so it can accept a lone pair. It is clearly not a Bronsted acid as it does not have a H+ to release on dissociation.
CCl_3 Lewis base
-H Lewis base
CH_2O Bronsted base
CH_3Cl Bronsted acid
-OCH_3 Lewis base
NH_3 is a Lewis Base:, N has a a lone pair which it can donate to a Lewis acid like BF3.
Explanation:
The Brønsted-Lowry theory describes acid-base interactions in terms of proton transfer between chemical species. A Brønsted-Lowry acid is any species that can donate a proton, H+, and a base is any species that can accept a proton. As for chemical structure, this means that any Brønsted-Lowry acid must contain a hydrogen that can be dissociated as H+. To accept a proton, a Brønsted-Lowry base must have at least one solitary pair of electrons to form a new bond with a proton.
Elements that make up the compounds that are characterized as covalent are mostly in the right part of the periodic table.
Alkalyne metals and alkalyne earth metals, which are located in the left part of the table, and given that those elements form ions with relative ease they make up ioinic compounds.
Covalent compounds are made up mainly of a non metal element and a metal elements with low metallic properties.
The metallic character of the elements decrease as you go to the right of the periodic table, that is why you found those elements in the right part of the periodic talbe.
