Classify the following substances as a bronsted-lowry acid, bronsted-lowry base, lewis acid, and/or lewis base. hcl, bf_3,ccl_3, -hch_2o, ch_3cl-och_3 , nh_3

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.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
